[PATCH 5/6] json-writer: include strbuf-safe.h

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <stolee@gmail.com>

We will use json-writer.c as our first 'safe' API, after removing some
unsafe methods that reach die(), especially the strbuf API. However, the
fact that json-writer.h includes strbuf.h causes someheadaches here.

Normally, we would only declare 'struct strbuf;' as a way to anonymously
define a struct and have implementations include the full header as needed.
However, 'struct json_writer' needs the full struct info and
JSON_WRITER_INIT needs access to STRBUF_INIT.

Thankfully, both are included in strbuf-safe.h, so we can have the header
include the safe API and move an include of strbuf.h to json-writer.c.

However, this has some implications to the trace2 API that includes
json-writer.h and implicitly depends on that includes of strbuf.h. Have
those files include strbuf.h directly to compensate.
